Mr. & Mrs. Smith meets political thriller in this heart-pounding series debut about two undercover flames whose new mission risks exposing their true identities to the world…and, worse, each other. Caspian Anderson is a translator for the United Nations—or so he’s led everyone to believe. No one suspects that mild-mannered Caspian, with his baggy clothes and sensible car, is actually an elite assassin for the US government. And that’s just how he wants it. For ten years, Caspian has worked under the code name Elias for Onyx, a black program deep within the Department of Homeland Security. His latest mission takes him to Switzerland to kill a target tied to a human trafficking ring. There, Caspian stumbles onto a web of conspiracies involving high-level political figures. Meanwhile, Caspian’s girlfriend is starting to pull away, and he wonders whether she may have secrets of her own. The truth is, Liesel Bergmann’s a spy. But neither knows the truth about the other…yet. As their covert operations converge, trust becomes paramount. Can they work together to bring down the enemy with their lives—and hearts—still intact?

The bestselling author of The Elias Network returns with a globe-trotting thriller about a retired assassin called back into action in order to save everything he holds dear. Caspian Anderson, once a black-ops assassin known as Elias, now works for the Defense Clandestine Service. But unfinished business dies hard. Glimpsing a familiar face while tying up loose ends overseas, he swears it’s his lover, Liesel Bergmann—a German spy and erstwhile collaborator. But back stateside, he can’t ask her without giving himself away. This mystery hangs between them as they kick off a new mission to unravel a global criminal conspiracy, one that implicates Caspian’s own parents. Dispatched to France, they must track down rogue start-up founder Frank LaBelle before his cutting-edge defense tech falls into the wrong hands. But when Caspian’s team is compromised by friends and foes, he’s left with no one to trust but himself. And to complete the mission—and save the world—he resurrects the deadly Elias. Action packed yet intricately plotted, Simon Gervais’s The Elias Enigma deftly probes the mercurial nature of truth among spies and the lies we tell for love.
